Doug Yule was born in Mineola, New York, and grew up in Great Neck[1] with five sisters and a younger brother. As a child he took piano and baritone horn lessons. He later said in an interview that he would have preferred violin lessons, but the violin had to be rented and the baritone horn was available free of charge.[2] In high school he played the tuba, as well as the guitar and the banjo, and sang in the church choir.[3]

Yule first met the Velvet Underground at his River Street apartment in Boston, which he happened to be renting from the Velvets' road manager, Hans Onsager. The band would sometimes stay there when they played in Boston. At the time, Yule was constantly practicing on his guitar. Sterling Morrison noticed how much his playing had improved over time, and mentioned it to Lou Reed.[6]

When John Cale left the Velvet Underground at the behest of Lou Reed in 1968, Yule joined the band (then consisting of Reed, Morrison and Maureen Tucker) as Cale's replacement. Yule made his first studio appearance on their third album, The Velvet Underground (1969), playing bass and organ, as well as singing lead vocals on the ballad "Candy Says" which opens the album, and co-singing the chorus of the album's penultimate track, "The Murder Mystery", with Maureen Tucker. Yule's contribution to the LP was considerable, and his vocals would later come in handy on the road. When Reed's voice became strained from touring, Yule would sing lead on several songs. While Cale had been a more experimental bass player, Yule was considered more technically proficient on the bass than Cale[by whom?][citation needed] and his distinct melodic style suited Reed's desire to move the band into a more mainstream direction. Yule's lead vocals can be heard on the song "She's My Best Friend" which was recorded in 1969 and later appeared on the outtakes compilation "VU", and on the band's fourth album, Loaded (1970), Yule's role became even more prominent, singing the lead vocals on several songs on the LP ("Who Loves the Sun", "New Age", "Lonesome Cowboy Bill", and "Oh! Sweet Nuthin'"), and playing six instruments (including keyboard and drums). Yule's brother, Billy, also joined in on the sessions as a drummer, as regular drummer Maureen Tucker was pregnant and therefore absent for most of the recording. Yule's lead vocals can also be heard on the song "Ride Into The Sun", which was featured on the Fully Loaded CD reissue of Loaded that was released in 1997.

Lou Reed left the Velvet Underground following the final show of the Velvets' Summer residency at the New York club Max's Kansas City in August 1970. With band manager Steve Sesnick looking to fill pending bookings, and with the upcoming release of Loaded in November of that year, Yule, Tucker and Morrison decided to continue performing as the Velvet Underground to promote the album. Yule took over lead vocals and switched his main instrument from bass to guitar, and Walter Powers was recruited as the Velvets' new bass guitarist. Following the release of Loaded in Europe in the spring of 1971, Morrison left the group in August to resume his academic studies in Texas, and was replaced by Willie Alexander on keyboards. Alexander, Powers and Tucker left the Velvets in late 1972 after being forced out by manager Steve Sesnick prior to a handful of European shows to promote Loaded in Europe. With no original band members left, and with a group of quickly assembled musicians, Yule played the final shows as the Velvet Underground in 1972. With Ian Paice of Deep Purple and some session musicians, Yule recorded the album Squeeze in late 1972. It was released in February 1973 in the UK only, and is in essence a Doug Yule solo album, though presented as a Velvet Underground album due to band manager Steve Sesnick's contractual agreement with Polydor, and due to the success of Live at Max's Kansas City, which had received positive reviews the previous year. After two final shows in early '73 that a promoter mistakenly billed as by "The Velvet Underground" (against Yule's wishes), the band was officially retired.

In 1974, Lou Reed contacted Yule to contribute a melodic bass track on his solo album Sally Can't Dance (1974),[5] (Yule's bass playing appears on the song "Billy", which closes the album), and at Reed's request, Yule joined his band for the subsequent US & European tour as his guitar player. Following the tour the band dissolved, but Yule was called back by Reed in 1975 to record several guitar and bass tracks for his upcoming album Coney Island Baby, the 30th anniversary re-issue of which includes the bonus tracks that feature Yule on bass and guitar.

In early 1976 Yule was tapped to do session guitar work on Night Lights (1976) by Elliott Murphy, and then he joined the band American Flyer later that year as their drummer and background singer.

American Flyer was an active country rock band from 1976 to 1978, and the band also featured the guitarist Steve Katz of Blood, Sweat & Tears. After securing a major-label contract with United Artists, and managing to interest George Martin enough to bring him on board as their producer, American Flyer's debut album "American Flyer" debuted at #87 on the Billboard Top 200, and they even scored a minor hit with their single "Let Me Down Easy" which debuted at #80 in 1976. Despite the promise showed on their first album, their follow-up album "Spirit of a Woman" (also produced by Martin) failed to chart as high, and didn't carry the momentum the label expected, and the band decided to hang it up.[7][8] After American Flyer disbanded, Yule retired from doing music full-time, and became a cabinetmaker and a luthier of violins.

When the Velvet Underground reformed in the early 1993, Sterling Morrison had campaigned for Yule's involvement, but Lou Reed and John Cale ultimately overruled him, thus leaving Yule off the band's six-week reunion tour of Europe, and the subsequent live album Live MCMXCIII. Following the continual interest in the Velvet Underground, and partly due to the publicity of the band's released box set Peel Slowly and See in 1995, Yule, who had, by then, moved to the San Francisco Bay area, returned to public life, again giving interviews to journalists and various fanzines about his time in the Velvet Underground.[5] In one of them, he wrote an obituary for Sterling Morrison, who had died in 1995.[9]

Yule was not included in the original line-up for the Rock and Roll Hall of Fame when the Velvet Underground were inducted in 1996, despite his involvement with the band's third and fourth albums, The Velvet Underground and Loaded. Despite this, Yule remains a member of the Velvet business partnership, and continued to give the occasional interview about his time in the group. After having taken up the violin, Yule began to record music again in 1997. A song called "Beginning To Get It" appeared on the benefit compilation A Place to Call Home in 1998.[8] He played some concerts in 2000, while the live album Live in Seattle was released in Japan in 2002. He also featured on Tucker's live album Moe Rocks Terrastock.

Yule currently lives in the Wallingford neighborhood of Seattle, Washington, with his partner Beth, his son Dan, and two dogs. He plays fiddle and builds violins. In 2006, in addition to his appearance with Mark Gardener, he played bass on a brief tour with the Weisstronauts, a Boston surf rock group. In 2007 he was playing in an old-time band called RedDog.
